Partitions get underreplicated, with a single ISR, and doesn't recover. Other brokers do not
take over and we need to manually restart the 'single ISR' broker (if you describe the partitions
of replicated topic it is clear that some partitions are only in sync on this broker).
This bug resembles KAFKA-4477 a lot, but since that issue is marked as resolved this is probably
something else but similar.
We have the same issue (or at least it looks pretty similar) on Kafka 1.0.
Since upgrading to Kafka 1.0 in November 2017 we've had these issues (we've upgraded from
Kafka 0.10.2.1).
This happens almost every 24-48 hours on a random broker. This is why we currently have a
cronjob which restarts every broker every 24 hours.
During this issue the ISR shows the following server log:
{code:java}
[2018-02-20 12:02:08,342] WARN Attempting to send response via channel for which there is

{code}
Also on the ISR broker, the controller log shows this:
{code:java}
[2018-02-20 12:02:14,927] INFO [Controller-3-to-broker-3-send-thread]: Controller 3 connected
to 10.132.0.32:9092 (id: 3 rack: null) for sending state change requests (kafka.controller.RequestSendThread)
[2018-02-20 12:02:14,927] INFO [Controller-3-to-broker-0-send-thread]: Controller 3 connected

to 10.132.0.12:9092 (id: 1 rack: null) for sending state change requests (kafka.controller.RequestSendThread){code}
And the non-ISR brokers show these kind of errors:
{code:java}
2018-02-20 12:02:29,204] WARN [ReplicaFetcher replicaId=1, leaderId=3, fetcherId=0] Error
